Title: The First Spectrum of a Protoplanet
Abstract: We propose 2017A GPI observations of HD 100546. Our recently accepted GPI publication confirms the existence of HD 100546 b. While much of the emission is consistent with a point source, the protoplanet's colors suggest it may be surrounded by circumplanetary emission. Furthermore, due to an unknown contribution of HD 100546's hot disk emission to its near-IR photometry, we cannot presently extract a calibrated spectrum of the protoplanet. Our new data will obtain spectroscopy of HD 100546 b at H and K, where it has previously been detected photometrically. We can provide the first insights into the spectral fingerprints of an infant planet, determining whether its spectrum resembles its natal disk or that of a fully-formed substellar object.
